Mammals are more recently derived amniotic chordates, with fur and mammary glands

Hominin evolution:
Brain volume increases over macroevolutionary events
(Misconception #3)
H.erectus migrated ~2 million years ago, followed by H.heidelbergensis
Newish Traits = Cooler body temperatures, less hair, even smaller jaws and teeth
Regional populations adaptions = surface area:volume by climate (regional), nose and lips shapes by climate, strait hair in cool climates, eye lid folds in Asian populations to protect eye from UV, thicker fat in arctic populations, large brain volumes in cold climates, reemergence of lactase, skin color and vitamin D synthesis by region, resistance to malaria, increased susceptibility to allergies/asthma
